IpCamera: New IP Camera Binding

[SaschaQ88 (Sascha)]

Is it correct that the HLS WEbview and Webstream is only working on mobile Phones?

I can see the stream on my mobile in my sitemap but not on my Chrome Browser on my Desktop PC.

@matt1

Does /ISAPI/System/IO/inputs/1 give you the same result?

EDIT: I am leaning towards calling it triggerExternalAlarmInput as what is does is change if it triggers on a high or a low state. Depending on which device you connect to the input it may be back to front…

I’m also interested in the use case of how you use that? Using it virtually instead of running real wires?

It is some time since I created this rules and as I remembered /ISAPI/System/IO and /IO was not the same but I will test it.

The usecase is that i have a Cat and when trying Cameras Motion sensing i get alot of false alarms.
So instead i use Bosch Pet Friendly PIR on the Alarm Input. I have also put up some extra PIR’s connected to Z-Wave Binary input device in areas where the Camera covers but not the first PIR.
When this PIRS sense motion I activate the Alarm Input of the Camera and the Surveillance Station start recording and i use text overlay to show what activated the recording.

@SaschaQ88 Chrome doesn’t have native HLS, you will have to install a plugin from the chrome store

@matt1

Does /ISAPI/System/IO/inputs/1 give you the same result?

Yes it seems to work in the same manner.’

@matt1

I am getting the hikvision / RCA / EZVIZ (DB1) camera going at the moment and it is good, but no events on a button push and the non standard resolutions because of fish eye means that google home does not want to cast the h264. Looking at work arounds to improve it at the moment, but it is working great and the gif can be cast (I would prefer to cast the GIF anyway even if it did work) and the motion alarm works well instead of a button push as it has PIR to cut down on false positives. There is also the ability to use Zwave sensor hacks to capture the button push. Cheap and very easy to setup and integrating in Openhab is very easy.

So glad you bought this doorbell… been waiting for this integration to the binding for ages
Getting a little lost in the thread as it’s so big now, where are you at now as I believed the events couldn’t be tapped into, hence why I originally started testing your mpeg motion detection.

I’m flashed with LaView firmware atm as the hik firmware didn’t support onvif at the time. Let me know any testing you want done

[matt1 (Skinah)]

New build 2020-07-18 has these changes:

• 2 New hikvision channels @tnemrap thanks for the suggestion, need this tested as my camera has no inputs.
• New config to allow a low res RTSP stream to be used for the ffmpeg alarms since the stream is not watched this help lower the loads.

@delid4ve @John_Siemon @bgilmer

Working doorbell: Hikvision DS-HD1

I thought it would be a good idea to start a dedicated thread for this camera and compile all the info related to using it in openHAB. The camera is sold under these names (the hardware is identical): HIKVISION DS-HD1 (has Onvif in its supplied firmware, use the older 200321-2020-03-31 firmware​) RCA HSDB2A EZVIZ DB1 LAVIEW LV-PDB1630-U (has Onvif in its supplied firmware) NELLY’S NSC-DB2 (has Onvif in its supplied firmware) LTS LTH-7132-WIFI If you buy a brand that is not marked as havi…

@matt1

2 New hikvision channels @tnemrap thanks for the suggestion, need this tested as my camera has no inputs.

Thanks @matt1 is works.
Would it be possible to revert

TRIGGER high OFF/low ON

to

TRIGGER high ON/low OFF

/Mike

[matt1 (Skinah)]

Only the labelling or also the functionality?

[sjef86 (Christian)]

How can i make use of the ffmpeg functionality from withing docker container?

[tnemrap (Michael Parment)]

@matt1

Only the labelling or also the functionality?

Both

/Mike

[tnemrap (Michael Parment)]

I can do a pull request if you want.

/Mike

[matt1 (Skinah)]

I made the changes, so feel free to make your own build as I’ll wait till enough has changed to make another, in middle of making some changes.

[tnemrap (Michael Parment)]

Have problem to build, my IDE is at latest version.

[matt1 (Skinah)]

New build 2020-07-23 has these changes:

• Channel swapped for @tnemrap
• HLS changes for auto start of the stream.
• Bug fixes
• Improved Auto discovery of onvif cameras.

[MrTBone (Michael)]

Thanks @matt1! My previous connection problems with ONVIF version 2.20 have been resolved! The device connects now also with the new implementation just as it used two months ago with the old libs…

I will send you trace as this is possible now.

Events are as depicted below visible in ODM but the cellMotionAlarm does not capture this. Trace gives “Unhandled Onvif reply is…”

[tnemrap (Michael Parment)]

When debugging i am flooded of this

[matt1 (Skinah)]

@tnemrap

<EventNotificationAlert

The first one is interesting as it should always start with --boundary and yours is not. Do all your alarms work fine? DO they go back to OFF after <15 seconds after the alarm turns on? That message is the camera saying all alarms are now OFF and it should repeat every 10 seconds after alarms have stopped. The fix for this is simple but it may be all alarm messages are not getting handled and not just this one message so before coding further I would like to confirm the above.

@tnemrap

Selector.select() returned prematurely 512 times in a row;

That I see only very occasionally, less than 1 entry in my log per week so this means I have never narrowed down the cause. Do you see any patterns that form that make it go away or get worse? Any feature not work or glitch when this happens? How do you use your camera? ie you display a mjpeg stream 24-7 on a tablet or you use the mp4 recording feature all the time?

[delid4ve (Dave)]

Hi @matt1
Been trying to get to the bottom of why my openhab crashes, at first i thought it was amazon echo control but now I’ve investigated its something here (when adding a camera):

Something like that is best in its own thread as I only know a small area of Openhab and it is something I have never seen and in this case I doubt it is a bug in the binding but a java limitation possibly you need to increase a setting ?!?! First search the forum for java.io.IOException: Too many open files and you find this has been posted before, check for answers in those posts before opening a new one.
